Hey guys new to the site.

So i have a 98 beetle that had a bad fuel pump. I changed the pump with a OEM one and made sure the fuses and relay where all good. When putting the car in to accessory mode i can hear the pump priming but i'm not getting any fuel when i check the fuel rail lines. Does anyone have any ideas? Could it be clogged? Has anyone dealt with this before?

Thanks for the help guys.

How old is your fuel filter?

How much fuel is in the tank; what brand, fuel pump did you buy? Are the fuel lines; hooked up correctly? If you get them connected backwards; the car won't start and no fuel will come out of the line (return, instead of the feed fuel line).

Fuel tank is nearly full. Its a OEM pulled from a known working beetle. I don't think i mixed up the lines, but if there is a photo of the line orientation i would love to see it.

Hmm, a used fuel pump, could definitely be suspect; I would hook up a fuel pressure gauge and see what the pressure is. You typically, can rent a fuel pressure test kit; from many auto parts stores for free. You could test both the return and feed or what you think is the right one. A used fuel pump is suspect and there different types, part numbers, over the years; have you confirmed, that the pump is the correct one? If you decide to replace it with a new one; stick with VDO or Bosch, VDO, makes them for VW and we have found many aftermarket ones, to not work correctly or prematurely fail.

You might post the part number; of the new/used pump and confirm, it is the right one.

The VW parts site; lists this as the correct part #, for currently made replacement fuel pumps;

Part Number: 1J0919087J
Supersession(s): 1J0-919-087-J; 1J0919087H

Any results from testing done? Any VW/Audi or VDO logos; then, possible VW or other part numbers on the top of the pump? Ultimately, you need to confirm; that it is working, a fuel pressure test kit, would be the next thing to try.

Question. I noticed that the gas tank was filled to the top when changing the fuel pump. Could this damage the pump?

So, you mean a full gas tank or overfull? Did it come out; when you removed the old pump? In general, the pump would be ok but overfilling, has a tendency to affect the charcoal canister and clog up the gas/evap venting system, which can can, cause problems filling up the tank or throw a trouble code, for the evap system. If the venting or canister gets clogged; it will act like it is full, when you try to fill up, at the gas station (pressure will kick off the pump; like you have a full tank).

A crank sensor being bad; could kill the ignition spark, have you checked for spark?
